Abstract
Disclosed is a method and a system for rendering content on external devices securely. The method comprises setting up a communication channel between a proxy rendering server of a mobile device and an external rendering server of an external device, authenticating at least the external rendering server and upon successful authentication transferring a key from the proxy rendering server to the external rendering server, transferring the content encrypted with the transferred key from the proxy rendering server to the external rendering server for rendering the content, wherein the rendering of the content is performed in one of two modes, either in a preprocessing mode or in a non-preprocessing mode, and wherein a DRM agent is only present in the mobile device.

26. A method for rendering content, comprising the steps of:
-
setting up a communication channel between a proxy rendering server of a mobile device and an external rendering server of an external device; authenticating at least the external rendering server and upon successful authentication transferring a key from the proxy rendering server to the external rendering server; transferring the content encrypted with the transferred key from the proxy rendering server to the external rendering server for rendering the content, wherein the rendering of the content is performed in one of two modes, either in a preprocessing mode for performing processing of the content by the mobile device prior to transferring the content to the external rendering server, or in a non-preprocessing mode for performing processing of the content by the external device subsequent to receiving the content, and that a digital rights management (DRM) agent for digitally managing permissions associated with the content is only present in the mobile device. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. An electronic device for facilitating rendering of content in an external device, the electronic device comprising:
-
a processor; application software adapted to be executed by the processor for generating a request for rendering content, a rendering server for receiving the request for rendering content, a digital rights management (DRM) agent for verifying license credentials, a proxy rendering server for setting up a communication channel with the external device and transferring content, wherein the electronic device is adapted to facilitate the content rendering in one of two modes, either in a preprocessing mode for performing processing of content by the electronic device prior to transferring the content to the external rendering server, or in a non-preprocessing mode for performing processing of content by the external device subsequent to receiving the content, and that the DRM agent for digitally managing credentials associated with the content is only present in the electronic device. - View Dependent Claims (48, 49, 50)
